Application of GNSS for Vertical Reference Determination

Creator:: Kim, Su-Kyung
Abstract:: Vertical datum is a reference system used for specifying the elevation of specific points on or near the Earth. Precise and accurate definition and realization of vertical references are, therefore, crucial to ensure consistency between height measurements. The vertical datums can be divided into two categories: 1) vertical geodetic datums...

An ultra low power frequency reference for timekeeping applications

Creator:: Oporta, Hector Ivan
Abstract:: An ultra low power crystal oscillator that provides a frequency reference for battery powered timekeeping applications is presented. An amplitude control circuit is employed to ensure that minimum current is consumed. A subthreshold voltage regulator provides a supply voltage for the oscillator with minimum current consumption. The oscillator and regulator...

Historical disturbance regimes as a reference for forest policy

Creator:: Thompson, Jonathan R.
Abstract:: Using the historical range of forest conditions as a reference for managing landscapes has been proposed as a "coarse-filter" approach to biodiversity conservation. By emulating historical disturbance processes, it is thought that forest management can produce forest composition and structure similar to the conditions that once supported the native biota....

Exploring the Differences between Lagrangian and Eulerian Reference Frames for Stream Temperature Data

Creator:: Egan, Fey Frentress
Abstract:: Stream temperature research relies on reference frames in which to project data. An important decision in the project design is which frame of reference to use. This aspect of research planning is not always given the consideration of thought that would lead to the best decision. In this thesis, two...

Site specific reference person parameters and derived concentration standards for the Savannah River site

Creator:: Stone, Daniel K.
Abstract:: The U.S. Department of Energy (DOE) Order 458.1 states that the compliance with the DOE annual dose limit of 1 mSv (100 mrem) to a member of the public may be demonstrated by calculating dose to the maximally exposed individual (MEI) or to a representative person. Historically, the MEI concept...

Effects of pesticides on amphibians with special reference to the pyrethroidinsecticide, cypermethrin

Creator:: Biga, Lindsay M.
Abstract:: Pollution by pesticides is a ubiquitous concern for wildlife. The effects of pesticides are especially concerning in aquatic environments, which are particularly vulnerable as they have several exposure routes for the influx of chemicals. These effects are of particular concern as biodiversity loss reaches unprecedented rates. This includes recent declines...

Growth, residence, and movement of juvenile Chinook salmon within restored and reference estuarine marsh channels in Salmon River, Oregon

Creator:: Hering, David K.
Abstract:: Tidal wetland channels provide rearing habitat for juvenile Chinook salmon as they emigrate from freshwater habitat and prepare to enter the ocean. Widespread diking and drainage of estuarine marshes for agricultural and urban development may have contributed to a decline in salmon abundance in the Pacific Northwest, prompting efforts to...

Spatial relationships for vegetation in restored and reference salt marshes in the Salmon River Estuary, Oregon

Creator:: Chellew, Megan
Abstract:: In this thesis, the spatial patterns of vegetation and soils of reference and restored tidal marshes were compared to determine the extent to which restored sites differ from the reference site after 40 years of restoration. Vegetation surveys of 1m x 1m plots were conducted along previously-established transects of salt...

Comparison of dosimetric modeling of the International Commission on Radiological Protection trout reference animal

Creator:: Comolli, Michelle LeAnne
Abstract:: Radiation protection has historically been from a human protection approach, therefore many studies have neglected the potential dose contribution from the gastrointestinal tract (GIT) in animal studies. The International Commission on Radiological Protection (ICRP) utilized simplified geometric shapes with Dose Conversion Factors (DCF) based on homogenized models for the trout...

Evaluating Methods of Aligning Real-Time GNSS Networks to the National Spatial Reference System

Creator:: Ohene, William
Abstract:: Aligning Real-Time Networks (RTNs) with the National Spatial Reference System (NSRS) is crucial to ensure accuracy, consistency, interoperability, and long-term data integrity for geospatial applications. However, the effectiveness of different alignment methods as well as the need for monitoring approaches to maintain alignment consistency with the NSRS have not yet...
